Assessing complications and functional outcomes in proximal humerus fracture management: a retrospective comparison between conservative and intramedullary nailing treatments.

INTRODUCTION: Fractures of the proximal end of the humerus (FPH) are the second most common fractures in the upper limb after fractures of the distal radius and are two to three times as common in women than in men. Therefore, the main objective of the present study was to compare and analyze the complications and the functional outcomes in patients with displaced FPH receiving conservative and surgical treatments with intramedullary nailing. METHODS: A retrospective cross-sectional study was conducted to establish the differences in complications risks between surgical and non-surgical treatment of the FPH. For this purpose, the clinical and radiological results of 67 consecutive patients were analyzed. RESULTS: A total of 25 patients were included in the non-surgically treated group. A total of 42 patients were included in the surgically treated group. Complications occurred in a total of 4 (16.0%) patients after the non-surgical treatment. Those included frozen shoulder (n = 2), nonunion (n = 1), and avascular necrosis of the humeral head (n = 1). Complications occurred in a total of 18 (42.6%) patients after the surgical treatment. Non-surgically treated patients had statistically significantly (p < 0.05) lower scores in the Constant-Murley scale in all of the categories. CONCLUSION: The present study demonstrates an overall prevalence of complications to be 16% in patients treated conservatively and 42.6% in patients treated surgically. In the non-surgical cohort, the frozen shoulder was the most frequently observed complication (8%). Interestingly, non-anatomical repositioning was the most prevalent complication in surgically treated patients. Due to the complexity of the FPH, we believe that the surgeon needs to have comprehensive knowledge regarding the characteristics of this fracture, the available treatment options, and the possible complications that may occur. This can enhance patient safety and provide satisfactory clinical outcomes.

Classification of intraarticular calcaneal fractures: comparison of two classification systems.

PURPOSE: Accurately classifying displaced intraarticular calcaneal fractures (DIACFs) is essential for orthopedic surgeons to choose optimal treatment methods and provide results evaluation and communication. Many authors studying used Sanders classification reported moderate intra- and interobserver reliability. Taking the software opportunity of 3D virtual exarticulation, Goldzak updated French tri-dimensional Utheza classification, providing an alternative framework for classifying DIACFs. The aim of this study was to compare the intra- and interobserver reliability of Sanders versus Goldzak classification systems. METHODS: The CT scans of 30 patients with displaced intraarticular calcaneal fractures, treated in the same trauma center between 2014-2018, were analyzed by 16 medical doctors (specialists and residents in orthopedic surgery, specialists and residents in radiology), and classified according to Sanders and Goldzak classifications. The same images were sent on two separate sessions, in a randomized order. Interobserver reliability and intraobserver reproducibility were assessed using Kappa statistics and Gwet's AC1 coefficient. RESULTS: Interobserver reliability using Gwet reported a value of 0.36 for Goldzak classification and 0.30 for Sanders classification (corresponding to "fair assessment" in both cases). In absence of subclasses, "substantial assessment" was reported for Goldzak classification (Gwet of 0.61) and "moderate assessment" for Sanders classification (Gwet of 0.46). Goldzak system had a greater interobserver reliability in the group of radiology residents. Intraobserver reliability coefficient was 0.60 for Goldzak classification and 0.69 for Sanders classification, indicating a substantial agreement for both classifications. CONCLUSION: Despite the better view of the fracture lines provided by 3D reconstructions, this study failed to prove the superiority of Goldzak classification compared to Sanders classification for DIACFs.

Optimal use of transmedullary support screws and fibular management in distal tibial fracture nailing based on a new biomechanical classification.

INTRODUCTION: Based on a novel simple frontal view classification, a comprehensive concept for systematic management of intramedullary fixation of distal tibial fractures is introduced. Even the usage of thin (unreamed) nails allows for anatomic reduction and stable fixation if applied in combination with transmedullary support (TMS) screws. Our classification system guides the placement of the TMS screw (medial or lateral) and suggests whether to fix the fibula or not. PATIENTS AND METHODS: The fixation concept of the classification was applied to 67 distal tibial fracture cases. Patients were followed up until nail removal after at least 12 months. RESULTS: All fractures united. Besides 5 cases of slight external malrotation (<5 degrees) no axial malunion was found. Two infections were encountered, but both were treated effectively by exchange nailing, antibiotic therapy until wound healing and C-reactive protein normalization. Final functional assessment according to Olerud/Molander Score was 85 pts (100 pts. possible, range 50-100 pts). DISCUSSION: The stability we achieved even with single screw interlocking was high due to anatomic reduction with interfragmental compression in the lowest fracture line. In cases of fracture extension into the ankle joint, interfragmental compression screws were applied before nail insertion. In more comminuted fracture types additional screws are advisable. CONCLUSIONS: The frontal view classification has proven to be a reliable guideline for effective intramedullary fracture fixation by minimally invasive means, allowing for optimized soft tissue protection.

Treatment of Displaced Intra-articular Calcaneal Fractures by Intramedullary Nail. Preliminary Report.

BACKGROUND: Open reduction and plate stabilisation is a recognised method of treatment of intra-articular calcaneal fractures. The surgical approach to the calcaneal bone used in these procedures is associated with a high risk of complications. The aim of this paper is to present the author's experience with a new surgical method and analyse early outcomes of the treatment of calcaneal fractures by Calcanail intramedullary nailing. MATERIAL AND METHODS: The study encompassed 17 patients (5 women and 12 men) with 18 calcaneal fractures (5 in the right foot and 13 in the left foot). The mean age of the patients was 47 years (range: 22-68 years). The mean time between the injury and surgery was 6 days (range: 3-14 days). The mean duration of follow-up was 12 months (range: 6-18 months). The fractures were classified according to the system presented by Guy Utheza. RESULTS: Bone union was achieved in all patients within 12 weeks of surgery. No infectious complications were observed. The mean AOFAS score was 82/100. Mean Bohler's angle was -3 degrees pre-operatively and +29 degrees post-operatively. CONCLUSIONS: 1. The use of Calcanail intramedullary nailing in the treatment of displaced intra-articular fractures is a minimally invasive procedure associated with a low risk of complications. 2. The innovative posterior approach allows for the intrafocal reduction of an articular surface fracture through the prepared intramedullary canal.
